IMPROVEMENT IN ALCOHOL- LAMPS.

Specification forming part of Letters Patent No. 201,913, dated April 2,1878; application filed March 1, 1878.

To all whom it may concern:

Be it known that I, JOHN WILLIAM COOPER, of Salem, in the county ofWashington and State of Indiana, have invented a new and ImprovedAlcohol-Lamp, of which the following is a specification:

Figure 1 is a side elevation, partly in section, of my improved lamp.Fig. 2 is a front elevation, having a part broken away to more clearlyshow the construction.

Similar letters of reference indicate corresponding parts.

My invention relates to alcohol-lamps for soldering and similarpurposes; and it consists in a reservoir pivoted in a supportingframe,and provided with two wick-tubes.

It also consists in an extinguisher secured to a spring-support, andcapable of closing the larger wick-tube when it is in a verticalposition, and in an independent extinguisher for the smaller wick-tube.

It also consists in a novel device for projecting the wick from thelarger tube as it is moved out of a vertical position.

Referring to the drawing, A is a frame consisting of two similar sidepieces, a 12, connected by the curved bars 0. In this frame acylindrical reservoir, B, having convex heads, is pivoted axially.

A tube, 0, projects from one side of the reservoir B, and to it isfitted a wick-tube, D, which'projects downward into the reservoir. Oneside of the tube 0 is slotted, and one end of a wire, d, projectsthrough the slot into the side of the tube D. The other end of the wired is bent in the opposite direction, and is jointed to an arm, e, thatprojects from the side piece a.

A small Wick-tube, E, is secured in the side of the reservoir near andparallel to the tube (3. The tube E projects above the tube O.

A curved arm, f, is attached to the side piece a, and a plate, g, whichis fitted to the tube 0, is connected with the said arm by a spring, h.An arm, 2', is hinged to the plate g and attached to a cap, j, that isfitted to the small wick-tube E.

The reservoir B is provided with a fillingaperture, is, which is closedby the screw-cap Z.

The wick in the smaller tube may be kept constantly burning. When thelarger wick is to be used thereservoim B is turned on its pivots untilthe tube 0 is removed from under the plate g, and the wick-tube D isprojected from the tube 0 by the action of the wire d, when the largerwick will be lighted from the smaller one. 7

As the tube 0 is returned to a vertical position the wick-tube D isdrawn into the tube 0, and the larger flame is extinguished, while thesmaller one continues to burn.

When it is desired to extinguish the smaller flame the cap j is placedover the end of the smaller wick-tube. The smaller flame may be usedindependently of the larger one for the smaller kinds of work.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An alcohol-lamp having a pivoted reservoir, amovable wick-tube, and a fixed wicktube, substantially as shown anddescribed.

2. The combination of the stationary extinguishing-plate g and the lamphaving the pivoted reservoir B, as shown and described.

3. The combination of the supporting-frame A, pivoted reservoir B,having the fixed tube 0, sliding wick-tube D, and wire 07, substantiallyas shown and described.

4. The combination of the hinged arm i, cap j, and wick-tube E,substantiallyas shown and described. v
